Are there any best practices for optimizing array manipulation in PHP?

When working with arrays in PHP, it is important to optimize array manipulation for better performance. One way to do this is by using built-in array functions instead of manual loops whenever possible. Additionally, using associative arrays can improve readability and efficiency when accessing specific elements. 

// Example of optimizing array manipulation in PHP

// Using array_map() to apply a function to each element of an array
$numbers = [1, 2, 3, 4, 5];
$multiplied_numbers = array_map(function($num) {
    return $num * 2;
}, $numbers);

// Using array_filter() to filter elements based on a condition
$numbers = [1, 2, 3, 4, 5];
$even_numbers = array_filter($numbers, function($num) {
    return $num % 2 == 0;
});

// Using associative arrays for efficient element access
$user = [
    'name' => 'John Doe',
    'age' => 30,
    'email' => 'john.doe@example.com'
];

// Accessing user's name
echo $user['name'];
